For years Rawtherapee has been by choice for raw editing, but it does not seem to be able to work with a Datacolor Spyder Colorcheckr Photo 24 or 48. Does anyone know of a way to make this work, or to export an ICC profile from darktable or other software that can be used by RT? I’m photographing art work where color matching is critical. I guess the other option is to use darktable for this work, but I’m much more familiar with RT. Thanks.
You’d want to use some software to generate an ICC or dcp profile from the shots.
darktable’s functionality will not generate an ICC profile but instead works in dt’s pixelpipe.
Thanks. I gather that Lumariver will create an ICC or DCP profile, but it’s expensive just for that. Any other solutions that are either open source or reasonable in price? I run Linux most of the time, but occasionally boot into Windows from a separate drive. Other than that the solution is probably just learn darktable.
Lumariver is just the updated GUI of dcamprof…so you can use that for icc and dcp or argyllcms for ICC files
This one works for me in Windows 7:

Thanks. That looks a possible solution, but does it work with the Datacolor Spyder Colorcheckr? It also doesn’t claim to work past Win 10.
I have no idea, I don’t use that system.

It does…but you have to replace the colorchecker layout and data files with the spyderchecker ones but call them (rename them) colorchecker as that is what the program looks for …this is just a gui written to use argyllcms… so again you can use argyll or dcamprof if you are okay with a little commandline or use something like this…there is another one I have in my files as well that’s a GUI for argyll I will look it up… I can also write out the instructions on how to do this tonight or a bit later for you if its not obvious…

This is another one I have used some time back…actually looks to be a bit updated from the older version that I used…again just a GUI on top of dcamprof and argyllcms…I feel like support for dcamprof is maybe new…I might have to go back and check it out…

That would really be appreciated. I’m a bit lost on this. Also, some reviews say the Calibrite ColorChecker Passport Photo 2 is better than the Spyder. Does RoughProfiler even support the Spyder?
The software doing the work is argyllcms and dcamprof and they provide the necessary files for Spyder color checker cards

Just checking in…sorry I didn’t get a chance to sooner… Did you try roughprofiler with your spyderchecker… Just one note layout files provided with the supporting software for the spyder work with it in the “portrait” orientations so before you load your image or going forward to save you the step set it up with the white patch top left… Load the image draw the box, set the reference file to the spydercheck or SC24 if that is your version. Then you can read that in and it should map the patches…from there just run it to make your profile with the desired options… A tiff image will give you the icc workflow and a raw file or DNG will give you the DCP profile options…
Thanks to everyone who helped on this topic. I eventually returned the Spyder ColorCheckr and bought the Calibrite Passport 2 Photo. For now I’m just going with the simple workflow of converting the Nikon NEF files to DNG with Adobe DNG Converter, and creating DCP profiles with the Calibrite Camera Calibration software. Then I use these profiles in RawTherapee.
Pre-sales support from Calibrite was excellent. The tech wasn’t aware of RawTherapee before and was pleasantly surprised that it used DCP profiles as well as ICC. I sent him links to the RT website and the sections of Rawpedia on color profiles and color management.
